Definitions

  • the invention relates to a hip socket prosthesis, the bearing insert is held in an outer shell by a latching device comprising an undercut surface on the outer shell and an underlying, from the bearing insert obliquely outwardly to the opening side of the prosthesis standing elastic locking lip.
  • the invention has for its object to provide a hip socket prosthesis of the type mentioned above and in the preamble of claim 1, which is a backlash-free and yet tolerance-compensating Holder of the insert in the shell allows.
  • the undercut surface with the mounting device at the point of contact includes a smaller angle than the tangent to the line of deformation of the lip tip at the point of contact with the undercut surface, and the lip of the bearing insert is under bending deformation with her top self-locking in on the undercut.
  • the deformation line is that curve on which the lip tip moves under bending deformation of the lip under the force exerted by the undercut surface on its tip. This curve has at the point of contact the direction in which the lip tip attached to the undercut surface would move further outwards if the undercut surface were not present.
  • the mounting direction of the insert has been mentioned above. It does not matter which reference direction is chosen for the comparison of these two directions.
  • the central axis of the prosthesis is mentioned for this purpose in the claim, it does not matter how the direction of this central axis is determined in complex prosthesis forms, since it does not depend on the exact direction, if it is only fixed.
  • the lip tip exerts in the radial and in particular in the axial direction of an elastic force on the undercut surface whose reaction force pushes the bearing insert further into the outer shell until it reaches a play-free end position on a stop, for example, through the ground the acetabulum is formed.
  • the lip cooperates self-locking with the undercut.
  • the dimensions of the undercut surface and the lip are chosen so that even with the largest tolerance deviations meets the lip, at least on the undercut surface. This condition is easy to follow because the undercut surface can be made with an axial extent greater than any dimensional tolerances in that direction. It is further provided that all areas of the undercut surface, which are provided for contact with the lip tip, have a diameter which is smaller than the relaxed diameter of the lip tip.
  • the lip is flat inwardly away from the opening side of the prosthesis (US-A-5,507,828) and presses radially against the outer shell; the lip does not interact self-lockingly with the support surface and can slide outward and snap out under a force acting axially on the opening side of the prosthesis.
  • the undercut surface with which the lip of the bearing insert cooperates may be part of a projection, for example a bead, or a recess, for example a groove, in particular an annular groove.
  • the recess or the projection may be provided along the entire circumference or only in parts thereof, correspondingly, the lip may be designed as a ring lip or consist of a plurality of segments, which interact, for example, finger-like projections formed as projections.
  • the lip is disposed on the bearing insert and the undercut on the acetabulum, but conversely, the lip on the acetabular cup and the undercut on the bearing insert may be provided if the material properties so dictate allow.
  • the insert 2 is made of polyethylene or other suitable bearing material. Since this forms the lip in the present case, it should be elastically deformable.
  • the inner shape of the outer shell 1 corresponds to the outer shape of the insert 2 in such a way that the insert is adequately supported by the outer shell. In the example shown, they are spherical and lie against each other over the entire surface. This system should be guaranteed as free of play.
  • the insert 2 is held in the outer shell 1 by a latching device, which is generally provided with the reference numeral 3 in Fig. 3 and is shown in more detail in Fig. 4. It consists of an undercut surface 4, which is formed by a groove 5 in the inner surface of the outer shell, and a lip 6, which projects circumferentially from the insert and cooperates with the undercut surface 4.
  • the lip 6 has sufficient length to develop a suitable compliance, it is bordered by two grooves 7,8. It has a tip 9, which is intended to cooperate with the undercut surface 4.
  • the latching device 3 is arranged near the free edge 10 of the outer shell.
  • the insert 2 has a radially outwardly projecting Edge flange 11, which not only serves the reinforcement, but also the surgeon when inserting the insert in the outer shell 1 is helpful. Its rear surface 12 cooperates with a small clearance with the end face of the outer shell rim 10 and thereby enforces a position of use in the final stage of insertion, which approximates its desired end position and ensures that the lip 6 engages in the groove 5.
  • the lip 6 is in a relaxed, originally manufactured state (see Fig. 1 left) in cross section straight. Overall, it forms a cone whose tip faces the floor of the prosthesis. The lip is therefore obliquely outward to the opening side of the prosthesis.
  • the outer lip flank is provided in the relaxed, straight state with the designation A.
  • the lip 6 passes through a region 13 which has a substantially smaller diameter than the lip tip 9.
  • the lip is therefore strongly bent, as shown on the right in FIG. This strongly bent position is provided in Fig. 2 with the designation B.
  • the line 15 is drawn, on which the lip tip 9 is in the different deformation states.
  • This line is referred to in the claim as the deformation line of the lip tip.
  • the undercut surface 4 is arranged so that the deformation line 15 in any case, even taking into account the largest possible deviations of the bearing insert and the outer shell, meets this undercut surface.
  • their radius is relative to the radius the lip tip is chosen so that in any case that part of the undercut surface 4, which can be hit by the lip tip, has a smaller diameter than the lip tip. This ensures that in the mounted state, the lip tip always abuts under bending deformation of the lip on the undercut surface 4.
  • the undercut surface 4 includes with a parallel to the central axis 16 of the prosthesis extending reference line 17 is less than the angle ⁇ between this reference line and the direction 18, which corresponds to the tangent to the deformation line 15 of the lip tip at the contact point 19. This is the direction in which the lip tip 9 bearing against the undercut surface 4 wishes to continue to move.
  • the lip tip rests against the undercut surface 4, the inner boundary 20 of the groove 5 should always be at a sufficient distance from the lip 6.
  • angles at which the lip 6 and the undercut surface 4 cooperate are selected so that self-locking takes place or at least the force under which the lip 6 can slide back on the undercut surface 4 in the mounting direction is greater than the release forces must expect in use of the prosthesis, there is a guarantee that the insert 2 is always held without play in the outer shell 1. It is not necessary in that the lip 6 permanently retains the elastic force still acting immediately after the assembly. Rather, in polyethylene and similar materials is expected that this force gradually decreases. The holding effect is characterized but not or not significantly affected.
  • the angle ⁇ is suitably between 15 ° and 40 °, more preferably between 20 ° and 30 °.
  • the difference between the angles ⁇ and ⁇ is expediently not greater than 30 ° and is advantageously in the order of 20 °.
